09 Configuring server port for microservices - Spring Boot Microservices Level 1

Workshop recorded live on Jan 26, 2019. This course is still in progress.

How can we run two microservices on the same machine? We'll run into `port already in use" error, and we'll fix it by specifying a custom port.

Course: Spring Boot Microservices Level 1 - Communication and discovery

This course introduces you to building microservices with Spring Boot and Spring cloud. This is Level 1 - start here if you are completely new to building microservices in Spring.

I am amazed.
I saw this exact video a year ago just before I start fresh in my first job as a junior dev. Back then I was kiindaa understanding all these thing about configuring tomcat, .jar in production, etc etc...
Now I' m refreshing this for a better gig and oh boy, I understand all these things... It almost feels like I'm chit chatting with Kushik
"How was your day"?
"Nothing special, the usual stuff"
How different things are now after a year..oh boi...

Excellent Content. Crisp and clear explanation . I just faced a small problem while doing the hands on as I created the controller in a separate package. I think its worth mentioning here that, if the controllers are created either in the same package or sub package of the spring boot main application java , then spring boot identifies the controller automatically else we have to add an annotation @ComponentScan in the main springboot application java file.

Superb explanation and relaxing voice... what else do you need, haha :D

I really don't understand....for movie-catalog the url worked well, but for movie-info-service I get 404 when I try /movies/foo
I'm testing on the correct port, so I'm not mistakenly running on the other server
@RestController
@RequestMapping("/movies")
public class MovieResource {
@RequestMapping("/{movieId}")
return new Movie(movieId, "Test name");
}
}


The file is also in the same package, under the resources folder.
Can anyone help?

[omurduneto]

is the movie catalog service the api gateway?

[saurabhgoyal]

i have try with below comment but geting an error


@RestController
@RequestMapping("/movies")
public class MovieInfo {




{
return new Movie(movieId, "test set");
}


}




This application has no explicit mapping for /error, so you are seeing this as a fallback.

I still do not get it: when we run several microservice apps on the same machine, each of them starts with its own or a separate copy of a Tomcat? And those Tomcat copies are attached by default to the same physical port?

[nolediganamimadre]

what happend if I have a very big system with many diferents microservices. If i use spring boot I have to assign to it one diferent port? We gonna have dozenz and dozens of ports used?

[shahjadealam]

how can i run one micro-service on multiple port. like catalog-API should be running on 8081, 8082, 8083.

[amitdubey]

please share when to prefer Node.js and when to choose Spring boot

[priyankavaidya]

can we use boot to develop django microservice

[ganeshradiga]

Hi Kaushik, Saw you spring boot cli video, wherein you create spring boot applications using groovy files. Is there any way we can do the same using java classes.

[uma_r]

excellent editing. unwanted moments are trimmed.

[anurag]

Can we run multiple spring boot apps inside single tomcat server? If yes, how?

[thetechthirsty]

How to open multiple projects is Same window in intellij? Just as we do with eclipse?
